VALVE.

Application le d February To all elf/tout it may conce r11` Be it knownthat l, JEAN V. GinsLnn, a citizen of the United States, and resident ofKnoxville, Tennessee, have invented new and useful Improvements inValves, which invention is fully set forth in the followingspecification.

This invention relates to valves and, while capable of use with valvesot a variety of forms, has particular utility when applied to radiatorvalves et the quick-opening type.

lt has heretotore been proposed to provide a valve with cooperatingright and lett hand threaded members tor eiiecting a rapid openingl andclosing ol the valve by the rotation ot an operatinjg` member through360 or less. All constructions ot this type of which l am aware havebeen more or less complicated, expensive and ditlicult oit assei'nhly.lt is an object ot' this invention to provide a valve ot the typecharacterized ot simplified construction whereby the same may beinexpensively manufactured in large quantities and whereby theirassembly and adjustment are facilitated.

Another object of this invention is to provide a valve of the typecharacterized which employs a minimum number oit relatively movablethreaded connections .in the operating train ot' the valve` lt has alsobeen proposed heretofore to employ relatively movable reversely threadedmembers in the operating train of a valve ot the so-called packlesstype, but in all such constructions ot which I am aware the tlexiblewall forminga fluid-tight joint between the valve member and its casinghas been so subjected to rotative torque as to tend to rupture said walland destroy the fluid-tight joint. lt is an object of this invention toprovide a valve coniprising a flexible wall for 'forming a Vfluid-tightjoint between the valve member and its casing witlh cooperatingreversely threaded members for operating` the same so constructed andarranged that no rotal ive torque is transmitted to said :flexible wall.

A 'further object ot this invention is to provide a valve ol" thegraduated quick-opening type with an improved axially andcircuinterentially adj ustable inde plate whereby the same may beinitially set and subsequently adjusted to correctly indicate or controlthe positions of the valve.

(lther objects relate to the provision of a Serial No. 357,146.

valve olI the type in questionwhich may he readily assembled anddisassembled for in spection and repair and readily adjusted for theproper control o'l the flow of the heatingmedium; and one which, whilesimple in construction and inexpensive to make and assemble, is strong,durable and e'liicient in operation.

T he invention is capable of receiving a variety oli mechanicalexpressions, one`ol which is shown on the accompanying drawing, but itis to be'eXpi-essly understood that the drawing is tor purposes ofillustration only and is not to be construed as a delinition oi thelimits of the invention, reference being had to the appended. claims forthat purpose.

in said drawingz" Figj. l is a top plan view ot a valve embodying thepresent invention;

Fig. 2 is a vertical axial section through the housing of said valve;and

Fig. 3 is a bottom plan view of the member tor guiding` the movements oithe valve disk and predetermining the flow of the heating' medium.

ln the torni shown, wherein the invention is illustrated as embodied ina radiator valve et the graduated quick-opening` type, l designates avalve casing ot any suitable construction provided with an inlet 2 andthe usual tail-piece 3 for connection. to the radiator, retained inoperative relation to the outlet el by the nut 5. 'llhe bonnet portiono1 said casing may also be constructed in any suitable way, being' shownas comprised of two sections. The lower section 6 constitutes a housing`for the flexible wall to be de.- scribed and is threaded into the bodyportion ot said casing: and the upper section 7 is threaded onto saidlower section 6 and constitutes tie liXed member of the operating trainto be described hereinafter.

Said casing` l is provided with a suitable valve openingl e with whichcooperates a closure member or valve disk 9, ot. any suitableconstruction, carried by the disk holder l0. Said disk holder ispreferably provided with an extension ll which lits loosely within thevalve opening- 8 and serves the dual Yfunction ot guiding the closuremember in its movements and of controlling the flow oi the heating`medium through said opening. To perform the latter function, saidextension ll. may be given any suitable formation. As illustrated moreparticularly in Fig. 3, the extension 11 is shown as provided with fourwings 12 connected by curved portions 18 whereby the quantity of heatingmedium flowing through the opening 8 'tor each position ot the closuremember may be accurately predetermined. It is to be expresslyunderstood, however, that any other suitable form of guide member may beemployed if desired. The disk holder 1() is suitably connected to thelower end il ot the valve stem, which is desirably made separate -fromand has threaded engagement with the body portion 15 of the valve stem,said valve stem being attached to said disk holder in any suitable way,as by a split pin 16.

In the preferred embodiment of the present invention, the valve is madeof the packless7 type and to this end a flexible wall is providedintermediate the casing and the closure member and makes huid-tightjoints therewith. The flexible wall may be o't any suitableconstruction, being shown as a corrugated expansible and collapsibletubular wall 17 oit any suitable material, preferably resilient metal,lirmly gripped between the sections G and T ot' the casing to form afluid-tight oint therewith and firmly gripped between the lower portion1l and the body portion 15 ot the valve stem to form a fluid-tight ointtherewith.

T he body port-ion 15 of said valve stem is preferably made in two partswhich are llexibly connected in any suitable way. In the form shown, thelower part is provided with a T-shaped projection lo comprising a pinwhich engages in a corresponding slot in the upper part 19 ot said valvestem. To prevent rotation oil" said valve stem and, therefore, toprevent transmission o't rotative torque to the flexible wall li, saidupper section 19 ot' the valve stem is provided wit-h one or more ribsor projections 2O which engage in a corresponding slot or slots '2lprovided in the wall ot the section T ol the easing, said member lf) otthe valve stem being in eti'ect keyed to the section 7 ot' said casingto the end that the member 19 may have. axial movement with respectl tosaid casing` but may not rotate relatively thereto. The upper end ot'the member 1S) is provided with a coarse thread shown as a le lit-handthread, in engagen'ient with a correspondinj.)Y internal thread on acoojiieratingr member or nut 23.

The exterior wall of the section '.7 is also provided with a coarsethread 2l which is reverse to the thread on the nrmber 19 and therefore,in the lor'm shown, a right-hand thread. In engagement with the thread24 is a coojwrating hand-grasp member '25 provided with a`corresponding' interior thread. said member 25, in the torni shown`being' provided in any suitable way with a.. handle 26 for convenienceot operation. Said members 'n3 and are unitarily connected in anysuitable way so as in effect to crmstitute a single member con'iposed ottwo parts one surrounding the other. In t-ne lio-rm shown, the 'nut 23is provided with a peripheral flange 28 and the member Q5 is providedwit-h an upwardly-extending and inwardlydirected liange 29 which issuitably interlocked with the flange 28, as by the pin 30, to preventrelative rotation. T o prevent relative axial displacement ot saidmembers 's3 and 25 a cap 31 is threaded on to the projecting end ot themember 23 and bears on the upper sui-tace ot the inwardly-directedflange 29, a lock washer being` interposed between said cap and memberit desired.

To index and limit the rotation oli the operating' or hand-grasp member25, the latter is preferably provided with a projection or pointer 3?)and, nrounted on the section T ot the casing below the mem er is anindex plate. 3ft provided with an upi wardlyextending projection or pintor eoojieration with the projection 33. Plate 23st is also suitablyprovided with index marks as indicated in Fig'. 1. In order that saidindex plate 34 may be initially set and subsequently adjusted toaccurately indicate and control the movement of the valve. the indexplate 3l is preferably made axially and eircuniterentially adjustableand` to this end. is mounted to be 'freely movable longitudinally androtatably on the section T of the casing. Suitable means are provided loclamp said index plate 3ftin adjusted position. In the torni shown, asplit rino' Se embraces a downwardly-exteudiug flange on said indexplate and may be operated by a screw (not shown) received in theapertures 3T to release or clamp said ien-flex plate in any position towhich it may be n'ioved.

It will therefore be perceived that a valve structure has been providedwhich may be readily assembled. The flexible wall 17 may be readilyclamped between the lower portion 14 and the body portion 15 ot thervalve stem and between the sections 6 and T ot the easing and thesection 6 readily applied to the body portion ot the easing. The uut 253may be readily applied to the upper end ot the valve stem and. the indexplate Bil having' been previously clamped in position on tinx section 7by the split ring 3G, the operation' or hand-grip member Q5 may bereadily applied to the external threads on the section 7. The nut 23having been rotated until the closure member is in engagement with thevalve seat and n'i-ember having' been suit- Y ably positioned tocorrespond with the closed position ot the valve disk. the hole 'lor thepin can be readily drilled and the members 23 and Q5 interlocked by the.pin SO to prevent relative rotation,

The cap 31 can lil) then bc applied to the meinber 23 and, having beenscrewed tightly int-o position, prevents relative displacen'ient ot themembers il?) and The members 23 and 25 and cap 231 therefore constitu-tea unitary member the parts of which are eli'ectively locked againstrelative displacement.

In operation, the closure member or valve disk can be` readily operatedby rotating the member in one direction or the other. Rotation ot' saidmember is accompanied by an axial movement thereol owing to the coarsethread between said member and the casing section T, and axial androtative movement of said memberl 25 produces both axial and rotativemovement of the member El owing to the unitary connection therebetween.The axial movei'nent of member is transmitted to the vaive stem 15, andthe rotative movement ot' said member 23 pro (luces an additional axialmovement ot the valve stem owing to the coarse thread 2Q, between saidstem and the member 2B while relative rotation ot said stem is preventedb v the interlock provided by the ribs 2() and grooves 21. There-'forethe valve stem and the closure member connected thereto are movedaxially as a. result otl the compounded action ot' the reverse threadsand 24. Furthermore the open and closed positions ot the valve disk canbe accurately indicated and controlled by adjustment ot' the index plateZit which, upon loosening the split ring '36, may' be axially andcirc-uinierentiallv adjusted, and then clamped in adjusted position bytightening said ring 345. The eoaction oft pointer 335 and projection3.3 ett-eo tively limit-s the movement ot the. closure member, but theenga-gement of member 23 with member l5) may also be relied upon toprevei'it excessive movement oi the valve disk. llhereiiore. without theuse oiE cxccssively steep threads,y the valve may be e'liectively openedand closed b v a rotation et the operating meml'ier through 3600 orless. lVhile a single thread has been shown between the members l) andQ3 and between the member 25 and section 7, it to be understood thatdouble or triple threads may be employed if desired.

As rotation of the valve stem is positivelyY prevented by the engagementof the rib or ribs 2O and the slot or slots 21 no torque is transmittedto the flexible Wall 17, particularly Where said stem is made in twosections as shown and the section not in engagement with the flexiblewall is positively prevented from rotation. Therefore, the re* verselythreaded members are available tor operating a packless valve Withoutdanger ot rupturing the iexible member which provides the fluid-tightjoint.

1t will furthermore be perceived that a valve structure has beenprovided which em ploysonly two reverse threads inthe operating train ofthe valve disk, and which, While coinposed of a minimum number oi'simple parts which may be readily assembled and disassembled forinspection and repair, so that the valve may be inexpensivelymanufactured in large quantities, is strong and durable in constructionand capable foi' eiii ciently controlling the fiovv of the heatingmedium.

While the embodiment of the invention illustrated on the drawing hasbeen described wit-h considerable particular-ity it 'is to be expresslyunderstood that v'the invention is not limited thereto as the same i'scapable 4ot' receiving a variety ott mechanicalexpres sions, some ofwhich will now readily suggest themselves to 'those skilled in the art,While changes may be made in 'details ot form, arrangement andconstruction ot parts, and some ot the features used Without 'otherfeatures thereof, Without departing from the spirit of this invention.Reference is therefore to be had to the claims hereto appended for adefinition of the limits et the inveniton.
